How to fix "Cannot connect to Chaos Services"

Updated December 15, 2025 10:13

If you are seeing connection errors like:

Please check your internet connection, VPN, or firewall settings, then try again.
It seems that your network proxy is blocking the connection.

This means that your product cannot connect to Chaos to obtain a license. The most likely cause is a firewall, proxy or other security software is blocking the connection.

Error codes: -89, -90

Firewall allowlist

In your firewall or security software, allow access to the following:

*.chaos.com (including accounts.chaos.com, api.chaos.com, ols.chaos.com)
*.chaosgroup.com
*.enscape3d.com

Proxy configuration

Chaos Licensing can auto-detect PAC files or use a manual proxy configuration. You can change the proxy settings by editing the following config file:

Windows: %LOCALAPPDATA%\Chaos\UnifiedLogin\config.json
macOS: ~/Library/Application Support/Chaos/UnifiedLogin/config.json
Linux: ~/.config/Chaos/UnifiedLogin/config.json

A) Auto-configuration (recommended first)

If you use a proxy, enable auto-configuration to pick up the PAC file. The following settings can be used to detect PAC/WPAD automatically.

{
  "proxy": {
    "enabled": true,
    "url": ""
  }
}

B) Manual proxy URL

If auto-config fails, try to set a full proxy URL (scheme, credentials, host, port) in config.json. Use the full URI format, for example:

{
  "proxy": {
    "enabled": true,
    "url": "http://username:password@proxy.company.com:8080"
  }
}

Notes:

Include the scheme (http:// or https://).
Percent-encode special characters in usernames/passwords.
If your proxy uses OS credentials, you can omit username:password@ and rely on system auth.

C) No proxy

If you do not use a proxy, turn off proxy configuration:

{
  "proxy": {
    "enabled": false
  }
}

After editing config.json:
Quit and reopen the Chaos Login app (or restart the machine) to apply changes.

If you see 407 Proxy Authentication Required, sign in to the proxy or update proxy credentials.
